rebuilding LS6 for chevelle

[SS427]

Flat tappet cams have been an issue for many years now but I would try and find one of the few people that are grinding their own cams. There are names out there that can be trusted who are making good cams right now but don't use any of the major cam manufactures as I have had no luck with any of them. The solid lifter sound is what makes the LS6 Chevelle stand out. Quieting that cam ruins it for me. Like taking the whine out of an M22 or the sound of an Rolls Royce Merlin. Silence it and its just another engine.

My builder won’t even use flat tappet hes been building motors for some high end mustang people for a few years and has had to tear down and rebuild quite a few. He’s specifically not used comp in a few years on any build for that reason. I guess I need to either find an nos piece if I want to keep it authentic.

Talk to BTR , Brian Tooley Racing in Bardstown, Ky.. I put one of their camshafts in a 5.3 LS engine and so far no issues. Pretty sure they are grinding their own camshafts. Not sure if they’re into BB Chevy stuff.

Like Rick said: "The solid lifter sound is what makes the LS6 Chevelle stand out. Quieting that cam ruins it for me. Like taking the whine out of an M22 or the sound of a Rolls Royce Merlin. Silence it and it’s just another engine."

My last NOS LS-7 crate engine ate a NOS solid LS-6 camshaft due to excessive valve spring pressure on the new GM Aluminum heads I used on it. I then installed a Comp Cams hydraulic roller, and it never was the same, performance nor sound. Bill

I've had a high frequency hearing loss since infancy, so I have never, truly, heard a solid lifter camed engine. I could hear certain levels of ticking when I was younger, but that deteriorated over time and they all sound alike to me now anyway...
